Version Description
E-Series legacy
command
Usage Information
The shutdown command marks a physical interface as unavailable for trac. To discover if an interface is
disabled, use the show ip interface brief command. Disabled interfaces are listed as down.
Disabling a VLAN or a port channel causes dierent behavior. When a VLAN is disabled, the Layer 3 functions
within that VLAN are disabled. Layer 2 trac continues to ow. Entering the shutdown command on a port
channel disables all trac on the port channel and the individual interfaces within the port channel. To enable a
port channel, enter no shutdown on the port channel interface and at least one interface within that port
channel.
The shutdown and description commands are the only commands that you can congure on an interface
that is a member of a port channel.
